	A stepper motor controlled wire scanner assembly has recently been modified to support testing of the Brookhaven National Laboratory (BNL) Collider-Accelerator departments Energy Recovery Linac (ERL) beam position monitor (BPM) system. The ERL BPM consists of 4 9.33mm diameter buttons mounted at 90 degree spacing in a cube with 1.875 inside diameter. The buttons were designed by BNL and fabricated by Times Microwave Systems. Libera single pass BPM electronic modules, manufactured by Instrumentation Technologies, will be used to measure the X and Y transverse beam positions at 14 locations around the ERL. The wire scanner assembly provides the ability to measure the BPM button response to a pulsed wire, and evaluate and calibrate the Libera position measurement electronics. A description of the wire scanner system and test result data will be presented.
